[s-cars] Fwd: S6 Brake Master Cyl

Entirely different vehicle but very similar problem turned out to be a 
broken sensor ring on a rear axle.
Toyota Highlander with 70Km if anyone comes across this on their travels.

The brake fluid reservoir level was right at the seam which is just slightly above the "min' mark, which was enough to trigger the light. A jigger more brake fluid and no more light while driving.

The anti-lock system works fine on ice and snow, and I still get 44 pumps to hard pedal after shutdown. The hydraulic and brake fluids are at or slightly above their respective marks both running and stopped.
